Charl Schwartzel continued his good form with a second-place finish to Jean Hugo, who fired a course-record equalling ten under par 62 to win the Vodacom Business Origins of Golf event at Gardener Ross Golf and Country Estate.
Hugo made two eagles and six birdies on a blemish-free card for his 62 - in the process matching amateur Brandon Stone's 2009 mark - and it was enough to overturn the three shot deficit he had on Schwartzel going into the final round.
World Number 22 Schwartzel shot a seven under 65, but a frustrating pair of bogeys on the third and the 17th left him one shot adrift.
James Kamte also came to light with a charge, making seven birdies and a bogey in his six under 66.
He occupied third place on his own, four shots behind Schwartzel.
Titch Moore carded a 69 to take fourth place, and Jaco Ahlers, Jaco van Zyl and second round leaders Vaughn Groenewald and PG van Zyl shared fifth.
